14: Claims.

This invention relates to winding machines, and more particularly to improvements in machines for winding toroidal coils of the type in which the wire is wound on a closed ring-shaped core.

An object of the invention is to provide a simple, inexpensive and efficient machine for winding toroidal coils.

In accordance with the above object, one embodiment of the invention contemplates the provision of a toroidal coil winding machine in which alaterally split one-piece winding ring is rotatably supported upon a series of grooved rollers, one of which is mounted for lateral movement to laterally deflect one of the split ends of'the winding ring, whereby the ring is sprung open to permit the insertion of the core and the removal of the coil. The movable guide roller is mounted on a pivoted support, which also carries a wire guide which extends into the cen-- tral opening of the core for guiding the wire on the core.

Other features and advantages of the invention will become apparent from the following detail description when read in conjunction with the accompanying drawings, in which Fig. 1 is a fragmentary plan view of a toroidal coil winding machine embodying the features of the invention;

Fig. 2 is a fragmentary plan view, similar to Fig. 1, but with the winding ring shown in the open position;

Fig. 3 is a fragmentary side elevational view of the machine; 4

Fig. 4 is a vertical sectional view taken on line 4-4 of Fig. 3; and

Fig. 5 is a fragmentary sectional view taken on line 55 ofFig. l.

The winding machine illustrated in'the drawings comprises a one-piece winding ring l0, which is rotatably supported upon three grooved guide rollers H, l2 and i3 and is driven by a driving gear l5 connected to a suitable source of power (none shown). The inner surface of the winding ring is'formed with gear teeth H, H

for engagement with the driving gear, which is mounted on a horizontal shaft l8. This shaftand the stub shafts which support the two lower guide rollers I2 and I3 are rotatably Journa led in suitable bearings provided in a supporting interlinked with the core, the winding ring is closed and the core is clamped between a pair of clamp members 2525, only portions of which are illustrated in the drawings. These clamp members are adapted'to be oscillated either manually or by suitable mechanical means (not shown), whereby the core may be oscillated about its axis to distribute the wire thereon.

The winding ring is provided on its outer surface with a circumferential with storage groove 2'l that is capable of accommodating a predetermined amount of wire 28, which is wound on the winding ring after the latter has beeninterlinked with the core, as described above. Before starting the winding of the coil, the outer end of the wire on the Winding ring is attached to the core after being threaded through a wire guiding slot 29 of a slider 30 which is slidably mounted on one side of the winding ring. The winding ring is then rotated in the direction indicated by the arrow in Fig. 3, whereby the wire is withdrawn from the winding ring and applied to the core While the latter is oscillated to distribute the wire evenly thereon. As the wire is withdrawn from the winding ring, the slider 33 is caused by the wire to slide around the winding ring in a manner well known in the art.

For the purpose of guiding the wire and holding it taut as the slider approaches the core, the loop of wire between the slider and the core is yieldably pressed between a stationary vertical plate 32 and a spring plate 33. The latter plate is formed with a wire guiding finger 34, which extends into the central opening of the core and serves to guide the wire on the core.

In order to facilitate the opening of the winding ring to insert a core 24 and/or remove a i finished coil 35, the upper winding ring supframe 20, only portions of which are shownin the drawings.

The winding ring is formed of spring steel and has a separable transverse joint 22, whereby it ring-shaped core 24, upon which the wire is to be wound to form a toroidal coil. .Afterbeing porting roller H is mounted On a forwardly projecting horizontal arm 36 of an angular bracket 31, which is loosely mounted for pivotal movement on a vertical post 38 secured to the frame 20. The bracket has a second forwardly projecting horizontal arm 39 to which the spring plate 33 is attached. Thus, this spring plate and the upper winding ring supporting roller ll are movable with the bracket when the latter is swung about the vertical post 88. A handle 40 is provided on the forward end of the bracket arm 36 for convenience in manually shifting the bracket between the two positions shown in Figs. 1 and 2. The bracket is yieldably held ,in either of these positions by a set screw 42 which is secured to the bracket arm 36zand has a conical point 43 which is receivable in either of two conical depressions 44-44 in the frame 20 to hold the bracket in either of the two positions. A compression spring 45 is interposed between the upper surface of the. bracket and a nut 46 secured to the upper end of post 38. This spring presses downwardly on the bracket, thus holding the set screw 42 in one or the other of the conical depressions 44.

In Fig. 1 of the drawings, the winding ring is closed and the pivotal bracket 31 is in the position it assumes when the winding ring is closed. In order to open the winding ring to permit the insertion of a toroidal core and/or the removal of a toroidal coil, it is necessary to first remove all wire from the winding ring. The winding ring is then rotated to the position in which the. joint 22 is disposed on the front side of the ring and just below the clamp members 25, as shown in Fig. 3. Then, by means of the handle 40, the bracket arm 36 is lifted sufiiciently to disengage the holding screw 42 from the conical depression 44 and separate the winding ring at the joint 22. The bracket is then swung counter-clockwise (Fig. 1) to the position in which it is shown in Fig. 2, wherein it is held by the engagement of the holding screw 42 with the other conical depression 44. The upper winding ring supporting roller ll moves with the bracket arm 36, whereby the upper end portion of the winding ring, which is constrained to move with the roller, is deflected laterally r sprung open with respect to the lower portion of the ring, as shown in full lines in Fig. 2, and in broken lines in Fig. 4. The spring plate 33, being attached to the bracket arm 39, moves laterally outwardly with the defiected portion of the winding ring, so that the previously wound coil is freely removable from the wire guiding finger 34 as well as from the deflected end portion of the winding ring. Before closing the winding ring, another core 24 is slipped upon the wire guiding finger 34 andupon the deflected end portion of the winding ring, and after closing the winding ring by shifting the pivotal bracket 31 to the position shown in Fig. 1, the newly inserted core is clamped between the clamp members 25 and is thus properly positioned for the winding operation.

It will be obvious from the above description that a simple and convenient means is provided for opening the winding ring and for simultaneously shifting the wire guiding finger 34 with the deflected end portion of the winding ring to permit the insertion of the core and the removal of the coil. It should be understood, of course, that the invention is not limited to the specific embodiment thereof herein illustrated and described, but is capable of other applications within the scope of the appended claims.
